Fairway Driver · Understable vs Stable
The Axiom Insanity (9/5/-2/+1.5) and Innova Valkyrie (9/4/-2/+2) are both fairway drivers, and they fly similarly, with only minor differences.
Both are speed 9, so neither needs more power than the other to reach its flight. The Valkyrie is the more overstable of the two (stability 0 vs -0.5), so it fights wind and finishes harder to the left, while the Insanity flies straighter or turns more. Estimated maximum distance is about 111 m for the Insanity versus 105 m for the Valkyrie.
Choose the Valkyrie when you need to fight wind, throw forehand, or want a dependable finishing hook. Reach for the Insanity when you want a straighter line, an easier turnover, or more help at a lower arm speed.
